Solved Removing Security Pin And Reset To Factory Macbook Air 13 Early 2015

Chosen Solution

I purchased my MacBook Air 2015 from online and when I opened it, it as a security PIN needed. How do I remove this PIN and reset to factory. The owner doesnt know the PIN and curious if I upgrade the SSD (hard Drive) that could be an option?

To remove the firmware passcode you will need a programmer or another bios chip with a clean ME.
